Abstract (en)
The invention provides a railway car with superior riding quality by improving the flexural rigidity of the car body structure while suppressing increase of body structure mass. A reinforcing plate (7) is attached to a roof construction (1) on the side facing an inner side of the car body at a longitudinal center portion of a railway car body structure (10) composed of a roof construction (1), a side construction (2), an underframe (3) and an end construction (4). The range in which the reinforcing plate (7) is adhered in the longitudinal direction of the railway car body structure (10) is between two body bolsters (6), and the range in which the plate (7) is adhered in the horizontal direction of the roof construction (1) is approximately half the length of the roof construction (1) in the horizontal direction. The thickness of the reinforcing plate (7) is increased gradually as the height of the roof construction (1) in the vertical direction increases. According to this arrangement, the deformation of the roof construction (1) at the longitudinal center portion of the railway car body structure (10), which is excessive without the present arrangement, is suppressed, and the flexural rigidity of the railway car body structure (10) is effectively improved. In other words, the bending vibration of the railway car body in the vertical direction can be suppressed, and a superior riding quality is provided.
